safe
in
operation
and
operates
as
efficiently
as
possible,
a
regular
planned
inspection
and
preventative
maintenance
programme
of
the
equipment
is
essential.
Preventative
maintenance,
including
lubrication,
should
be
undertaken
at
pre
‐
set
intervals,
depending
on
the
crane
/
hoist
duty,
with
the
objective
of
keeping
the
equipment
in
a
serviceable
condition.
5.1
REPORTING
OF
DEFECTS
AND
INCIDENTS
The
competent
person
should
have
a
recognised
procedure
for
reporting
defects
and
incidents.
The
procedure
should
include
the
immediate
notification
of
the
following:
‐
1.
Any
defects
found
during
the

are
trained
and
competent
in
the
use
of
such
equipment.
5.3
KEEPING

procedures
and
control
of
replacement
stock.
Record
the
date
and
reading
on
the
hours
‐
in
‐
service
meter
each
time
a
component
is
replaced
and
the
reason
for
replacement.
See
section
7.8.
5.4
DAILY
PRE
‐
USE
INSPECTIONS
(at
the
start
of
each
day/shift)
Part
of
the
crane
operator’s
training
should
be
to
make
them
aware
of
potential
malfunctions
requiring
adjustments
or
repairs
and
the
need
to
bring
these
to
the
attention
of
the
competent
person
for
corrective
action.
The
crane
/
hoist
and
associated
equipment
should
undergo
daily
visual
and
functional
checks
to
ensure
that
they
operate
correctly.
These
can
be
executed
by
the
operator
from
floor
level.
1
In
the
event
of
a
malfunction
of
equipment
or
unusual
occurrences,
the
operator
should
immediately
REPORT
the
fault(s)
to
the
competent
person.
The
crane
should
be
taken
out
of
service
until
the
fault(s)
have
been
rectified
by
the
appropriately
qualified
personnel.
1.
Ensure
that
a
“
Men
Working
Overhead
”
or
a
“
Permit
to
Work
”
is
not
in
force.
2.
Check
all
round
visibility
and
carefully
note
both
permanent
and
temporary
hazards.
3.
Check
that
the
ropes
are
correctly
seated
in
the
rope
groves
of
drum
and
sheaves
and
have
not
been
displaced.
The
rope
should
be
free
of
kinks,
protrusions,
broken
wires
and
other
obvious
defects.
4.
Check
the
safety
latch
on
the
hook
for
damage.
5.
Check
that
no
electrical
equipment
is
exposed
to
contamination
by
oil,
grease,
water
or
dirt.
6.
Check
that
any
audible
and
visual
warning
devices
operate
correctly.
7.
Be
familiar
with
the
way
in
which
each
controller
functions.
Ensure
that
each
function
button
or
joystick,
including
the
emergency
stop,
on
the
controller
performs
its
stated
operation,
(without
a
load
attached)
and
that
each
button
or
joystick
returns
to
the
neutral
position
when
released
(except
emergency
stop).
Exercise
caution
whilst
making
these
checks
in
case
of
a
malfunction.
8.
Check
that
the
hoisting
and
lowering
limit
switch
device
operates
correctly.
To
do
this,
raise
or
lower
the
empty
hook
slowly
into
the
limit
position
to
test
its
operation.
1
Extreme
care
should
be
taken
when
performing
this
test.
Should
the
upper
limit
fail
then
there
is
a
possibility
of
damaging
the
hoist.
